Title: Method of treatment of liquid steel under vacuum
IPC: C21C7/10
Filed: 1968-07-26
Abstract: Steel is vacuum treated in a ladle 9, when covered by a layer of reducing slag 16, by immersing the lower extremities of 2 vertical refractory pipes 5 and 6. The upper parts of which open into the bottom of an evacuable, vacuum-tight, refractory, heat-insulated chamber 1 of cylindrical vertical cross section. Circulation of the steel is effected up the pipe 6 and down pipe 5 by means of a centripetal electromagnetic force acting towards the centre of the vacuum chamber 1 set up by passing an A. C. current through inductor windings 7 surrounding said chamber and within the metal casing 11. These windings 7 also heat the steel in the vacuum chamber by induction, and are themselves water-cooled, and are supplied with frequencies of 1-20 Hz for providing the circulation only or higher frequencies to act as a heat source. After treatment, the vacuum is removed by introduction of a neutral or reducing gas into the chamber after each vacuum treatment. To aid the setting up of the centripetal force the upward pipe 6 opens out into the bottom of a peripheral channel 10 around the base of chamber 1, the radial width of which is less than the thickness of the induced skin effect currents in the steel. The chamber is heated internally before each treatment by means of a coaxial, graphite ring 13 located inside the chamber and heated by induction by means of winding 14 outside the refractory chamber but within the metal casing 11 supplied with frequencies in the range 150-1500 Hz. Packs of magnetic iron sheets 12 are provided between the metal casing 11 and the windings 7 and 14, to channel the electromagnetic field on the interior of the metal casing but exterior of the refractory chamber and inductor windings. The process is started by sticking diaphragms of thin steel sheet over the lower openings of pipes 5 and 6, evacuating the chamber, and heating it to the required temperature. The vacuum is destroyed by introducing nitrogen or a reducing gas to the chamber and then immersing pipes 5 and 6 into the metal bath in a ladle and evacuating, and supplying current to windings 7. Additives can be introduced via a lock chamber 18, 19, 20. After treatment the vacuum is destroyed with nitrogen or reducing gas

Title: Arrangement for connecting an electric battery to a source of charging current
IPC: H02J7/00
Filed: 1968-09-06
Abstract: A battery charging circuit includes two semi-conductor amplifier elements in a symmetrical bi-stable circuit arranged to supply charging current to the battery terminals in a direction dependent on the connection of the battery. As shown in Fig. 1, the imput terminals 7, 8 poled as shown, supply a resistor 5 and conducting transistor 1 and a battery can be charged across terminals 9, 10 in series with a resistor 6 in parallel with resistor 8. If the battery is connected in the other direction the voltage applied through a resistor 3 renders the transistor 1 non-conducting and a transistor 2 conducts in series with the resistor 6. The potential applied to the battery terminals 9, 10 is thus in the other direction. Diodes (Fig. 2, not shown) may be connected in series with resistors 5, 6 to prevent battery discharge when the terminals 7, 8 are disconnected from the source. No damage occurs if the source polarity is reversed. The resistors 5, 6 may be replaced by two further transistors 15, 16 (Fig. 3) to form a symmetrical bridge with the transistors 1, 2 connected to have alternate arms of the bridge conducting and non-conducting. The transistors 1, 2 may be of the NPN conductivity type whilst the transistors 15, 16 are one of an opposite type.

Title: Pushbutton assembly for car radio
IPC: H03J5/12
Filed: 1969-08-14
Abstract: A push button set for a radio receiver has a plurality of push-buttons 1, each capable of actuating two driving rods 9, 11 13, 15 which are adapted to drive a tuning mechanism and on successive depressions of a push button the two rods are actuated alternately by an alternating mechanism 27, 31 and 47 adapted to engage first one and then the other of the driving rods. As shown a button 1 is in the released position after having been pressed to actuate via bolt 27 driving rods f3, 15. On next pressing the button 1, the gear 33 (Fig. 2) is moved anticlockwise together with driving gear wheel 31 which moves the bolt frame 27 to'the dotted upper position shown in Fig. 1 so that the button actuates rods 9, 11. The gear 33 now occupies the dotted position shown in Fig. 2 and is held against rotation by spring biassed driving pawl 35. The pawl 35 may be formed by two parallel beams 63. The rods such as 13, 15 may operate a known tuning setting arrangement (Figs. 5 to 7, not shown), in respect of which the modification draws attention to Patent No. 1,028,073. In this arrangement a segment adjusting element (51) is released from a locked position by pulling the button 1. The bolt 27 then engages the rod 13 and moves the rod relative to the rod 15 so that a U-shaped bracket (55) releases the adjusting element (51). The gear 31 and bolt frame 27 then occupy the lower dotted position in Fig. 1 and, although the gear 31 has moved, on repressing the button it resumes its position with tooth a against lug 47 for actuating rods 13, 15 so that the segment element (51) is rotated and locked to the new selected position of a tuning crank (59) by the U-shaped bracket (55). The bolt 27 may be in the form of a plate having projecting lugs 47, 49. Each driving rod 9, 11 and 13, 15 may have a lug which moves a spring returned slidable cover so that a light source is visible behind an aperture above that respective driving rod last pressed. The push button set may be used in a car radio.

Patent ES-422673-A1 (ES)
Title: Method for the production and/or testing of welded helical seam pipe
IPC: B23K9/127
Filed: 1974-01-28
Abstract: A method of producing welded helical seam pipe, made from steel sheet or strip which is wound into pipe formation, is disclosed. Prior to the welding of the wound steel sheet, an optically scannable reference line is applied to the steel sheet which extends parallel to and adjacent one of the edges of the sheet. The welding is effected by applying a first welding seam with a first welding head located within the pipe interior and a second welding seam with a second welding head located outside the pipe. In accordance with the invention, the optically scannable reference line is applied to that face of the sheet which forms the inner surface of the welded pipe. The thus interiorly located reference line is optically scanned so as to obtain scanning information which, through operative connection to control means, controls the welding movements or operation of both the first and the second welding heads. The inventive method is particularly suitable in the production of pipe which is tack-welded prior to finish welding.

Patent ES-448789-A1 (ES)
Title: Method for the production of blocks or bricks
IPC: C04B28/20
Filed: 1976-06-11
Abstract: In masonry bricks, the heat insulation can be increased by reducing the apparent density. However, this is at the expense of the strength of the blank. In order to obtain a reduced apparent density without impairing the strength of the blank, at least 1% by weight of cement, preferably fast-setting cement, is added to the raw mixture of sand, lime and water. In this modified mixture, strength-forming reactions of the cement are allowed to start by leaving the mixture to stand for, for example, 1 hour before compaction. Subsequently, the mass is compacted in a compacting device to give blanks, the pressures applied being low as compared with 150 kp/cm<2>. In this way, lime sand bricks can be obtained which have a proportion of more than 25% of voids and a strength of more than 1 kp/cm<2> and which can be handled without being damaged.
Patent ES-449268-A1 (ES)
Title: Elevator system
IPC: B66B1/30
Filed: 1976-06-25
Abstract: A traction elevator system in which the floor leveling device is active when the elevator door is open, and it is maintained active while the door is closing. The brake is partially released and the drive motor is activated when the elevator car receives a signal to start, and full release of the brake is initiated before the door, when closing, reaches the closed position, preparatory to a run. The leveling device, partial brake release and armature current buildup in the drive motor cooperate to provide a motor torque which exactly balances the unbalanced load, to hold the elevator car at floor level as the brake is fully released. When the door reaches the closed position, the car may be smoothly started without delay or "bump", as the brake is fully released and the unbalanced load is already compensated for.
